Abstract
A display panel includes a first halftone dot layer and a second halftone dot layer. The first and the second layers are formed with halftone dots printed at regular intervals in gradation patterns so that brightness gradually changes. The first and the second layers are arranged in parallel to each other yet rotated relative to each other by a predetermined angle measured between directions in which the halftone dots are aligned in the first and the second layers.
